Share your screen
Let others view your screen and control your Mac

You can let others view your computer screen on their own Mac. While your screen is being shared, the user of the other Mac sees what’s on your screen and can open, move, and close files and windows, open apps, and even restart your Mac.

  1. Open Sharing preferences if it isn’t already open (choose Apple menu > System Preferences, then click Sharing).

  2. Select the Screen Sharing checkbox.

    If Remote Management is selected, you must deselect it before you can select Screen Sharing.

  3. To specify who can share your screen, select one of the following:

    • All users: Any of your computer’s users and anyone on your network can log in.

    • Only these users: Screen sharing is restricted to specific users.

  4. If you selected “Only these users,” click the Add button at the bottom of the users list, then do one of the following:

    • Select a user from Users & Groups, which includes all the users of your Mac.

    • Select a user from Network Users or Network Groups, which includes everyone on your network.

  5. To let others share your screen without having a user account on your Mac, click Computer Settings, then select one or both of the following:

    • Anyone may request permission to control screen: Before other computer users begin screen sharing your Mac, they can ask for permission instead of entering a user name and password.

    • VNC viewers may control screen with password: Other users can share your screen using a VNC viewer app—on iPad or a Windows PC, for example—by entering the password you specify here.

      If this computer’s screen is shared only by other OS X users, turn off this option.
